Abstract: A packaging and method for controlling the seal strength between two cooperating thermo-sealable films at predetermined sealing portions, where a predetermined amount of heat is applied over a predetermined period of time. The resulting packaging is resealable after the first separation of two surfaces. The strength of the seal controlled by defining the number and dimensions of a plurality of restricted areas without a material cover that is resistant to the thermo-seal effect. The restricted area can be defined with a plurality of dots of predetermined selected shapes and dimensions. The resulting article facilitates the rupture of the packaging along a predetermined path. With this process, a fixed predetermined heat and residency time can be chosen and the seal strength can still be varied in different areas of a packaging. Non-sealable microdots with a predetermined amount of adhesive deposits also covered by a polypropylene powder deposit permit its resealing.

In EGTFC, the control unit changes a target value of intake throttling to a predetermined DOC IEGT T0. If application of a load exceeding a predetermined amount is detected before the DOC IEGT reaches the predetermined value T0, the control unit returns EGTFC to AIAFC.
